This invention relates to a device designed for sharpening razors, the construction of the device being such that the razor being stropped will be moved through the lines of force of the electromagnets forming a part of the stropping device, to the end that the line teeth of the razor edge, will be moved in a common direction parallel to the sides of the razor blade, thereby improving the cutting edge of the razor blade.

A further object of the invention is to provide a stropper of this character including an endless strop operated by an electric motor, to the end that it is only necessary for the person stropping the razor, to hold the razor on the endless stropper.

lVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a plan view of a stropping device constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view therethrough.

Figure 3 is an end elevational view of the device.

Figure 41 is a detail view of one of the adjustable bearings to permit of adjustment of the endless strop.

Referring to the drawings in detail, the device includes a base 5 constructed of suitable non-conductive material, the same having an ofifset portion 6 providing a support a for the electric motor 7. Positioned on the base 5, are the electromagnets 8 and 9 respectively, the magnets being spaced apart in such a Way that a razor blade to be stropped, may be held between the magnets.

Each magnet comprises a core 10, the adjacent ends of the cores being mounted on the upstanding portions 11 oi? the supporting member 12, which is constructed of nonmagnetic material. The outer ends of the cores 10 are secured to the supporting plates 13 that have their lower ends extended at right angles where they are supplied with openings to receive the securing screws 14: that secure the plates 13 to the base 5.

The cores of the magnets are formed with central cut out portions of widths slightly greater than the Width of the endless strop 6 15, so that the endless strop may move freely through the cores.

The endless strop 15 is supported on the rolls 16 and 17 respectively, the role 17 being mounted on the shaft 18 which operates 5 in the bearings 19 secured to the plate 13.

The roll 16 is mounted on the shaft 20 which has its ends positioned in the bearings 21 that are adjustably held in the bearing supports 22, there being provided adjusting screws 23 connected with the bearings 21 to move the bearings 21 to various positions of adjustment to remove the slack from the end less strop 15. v

The magnets are wound in the usual and well known manner, the windings being in circuit with a suitable source of electricity supply so that the magnetic forces will pass from the north to the south poles of the magnets, effecting the razor blade held between 30 the electromagnets.

In the use of the device the motor is set in operation, causing the endless strop 15 to move through the electromagnets, in the direction of the arrow as shown by Figure 1. 5

Electric current in passing through the windings of the electromagnets, sets up lines of force passing between the north and south poles of the magnets, and since the razor blade, which in the present showing is indib0 cated at A, is held within the path of the magnetic forces, it is obvious that the small teeth that form the cutting edge of a razor, will be influenced by the electromagnets, and 7 they will be moved to positions parallel with the sides of the razor blade being sharpened, insuring a true cutting edge.

I claim:

1. A mechanical stropping device comprising a base, electro-magnets mounted on the base, the cores of the magnets having bores extending longitudinally therethrough, rollers adjustably mounted near the outer ends of the bores of the magnets, said magnets being spaced apart to provide a space to accommodate a razor being stropped, an endless strop operating over the rollers, and means for operating one of the rollers to move the strop through the bores of the cores.

2. A mechanical stropping device comprising a base, electro-magnets mounted at the ends of the base, said electro-magnets having aligning openings, rollers supported on the magnets and in front of the openings, an endless stropping member extended through the openings of the magnets and operating over the rollers, the space between the inner ends of the magnets constituting a stropping space, and means for moving the stropping member through the cores.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

JOHN M. EZZELL.
